Hybrid Tea rose plant named ‘BAIpeace’

ABSTRACT

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms on a recurrent basis fully double blossoms that display a high center and an attractive blend of yellow and carmine pink coloration. The blossoms also display a sweet fruity fragrance. The plant exhibits a vigorous compact and upright growth habit, glossy dark green foliage, and good tolerance to Blackspot, Powdery Mildew, and Rust. The attractive dark green foliage contrasts nicely with the bicolored blossom coloration. The new variety is particularly well suited for growing as attractive ornamentation in parks and gardens.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Hybrid Tea rose plant was created at Yamhill, Oreg. during 1991 by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was an unnamed seedling (non-patented in the United States) from the breeding program. The male parent (i.e., the pollen parent) was the ‘Peace’ variety (U.S. Plant Pat. No. 591). The parentage of the new variety can be summarized as follows:

Unnamed Seedling×‘Peace’.

The seeds resulting from the above pollination were sown and plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification during 1993 of a single plant of the new variety having the distinctive ornamental characteristics hereafter described.

It was found that the new variety of the present invention:

(a) exhibits a vigorous compact and upright growth habit,

(b) abundantly forms on a continuous basis attractive fully double blossoms that display a high center and a blend of yellow and carmine pink coloration,

(c) forms dense glossy dark green foliage that contrasts well with the blossom coloration, and

(d) is particularly well suited for growing as attractive ornamentation in parks and gardens.

The disease tolerance is good with respect to Blackspot, Powdery Mildew, and Rust.

The new variety well meets the needs of the horticultural industry and can be grown to advantage in the landscape where attractive ornamentation is desired. The distinctive blossoms are displayed throughout the summer. The plant can be grown as a specimen or as a mass planting.

The new variety can be readily distinguished from other varieties including its ancestors. For instance, the blossoms commonly exhibit a deeper pink coloration than the ‘Peace’ variety and darker green foliage than the ‘Peace’ variety.

The new variety has been found to undergo asexual propagation by budding on an understock. Asexual propagation by this technique at Yamhill, Oreg., and at Phoenix, Ariz. has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another.

Initially the new plant was designated 91G55-1B. The new variety subsequently has been named the ‘BAIpeace’ variety, and is being promoted while using the LOVE & PEACE trademark. The new variety also has been named an All-American Rose Selections winner for the year 2002.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show as nearly true as it is reasonably possible to make the same in a color illustrations of this character, typical specimens of the new variety. The rose plants of the new variety had been propagated by budding, were approximately two years of age, and were being grown outdoors on Rosa ‘Dr. Huey’ understock.

FIG. 1 illustrates typical blossoms and foliage of the new variety while growing in a garden setting at St. Paul, Minn. during July. The blossoms in the foreground were in the final stages of opening and display the coloration blend of golden yellow irregularly edged with carmine pink. The attractive dense glossy dark green foliage additionally is shown.

FIG. 2 illustrates a typical single bud of the new variety in the early stages of opening while growing during July at St. Paul, Minn. The sepals bearing numerous extensions and glossy dark green foliage also are shown.

FIG. 3 illustrates from left to right typical flowers of the new variety in progressive stages of opening beginning with the bud stage. The plant was being grown during the summer while undergoing testing at Portland, Oreg.

FIG. 4 illustrates a typical open bloom of the new variety wherein the blend of golden yellow and carmine pink coloration is well illustrated. The plant was being grown during the summer while undergoing testing at Portland, Oreg.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). Common color terms are to be accorded their ordinary dictionary significance. The description is based on the observation of two year-old plants while budded on Rosa ‘Dr. Huey’ understock and growing outdoors during June and July at St. Paul, Minn. and during October at Phoenix, Ariz.
